Hitting boost for the first time in the turbo LS street truck build! It’s rowdy.

so today we are going to be wrapping up the turbo ls street truck build and we're gonna go start putting some miles on it getting the tune sorted out we might even be able to do some actual pools so that's what's in store we're gonna go get it registered tomorrow but in the meantime before that we've got a couple other things to finish up before this thing's truly roadworthy so a little recap if you're unfamiliar with this build or you haven't been following along i've had this truck for a few years now i use it as a temporary tow rig while i built my and swap ford dually so i told my open trailer with this it was a really good truck i bought it from my buddy derek he had already swapped a 6 liter and a 4l80e into it good truck man it pulled really well everything was great at some point along the way after i'd quit using it regularly just had it as a daily my girlfriend had to borrow it and the transcooler line popped off and dumped all the fluid out and burnt the trains up so it sat for a bit so on and so forth but the the plan the whole time the plan from when i bought this truck was to do this build uh this is a build i've wanted to do for four or five years now literally since i built my ls miata which if you follow along that you know it's a long time ago started watching slothing mechanics and ever since then i have wanted to do a build like this that's why i bought this particular truck as a temporary tow rig because i knew once i was done using it as a tow rig it would make a great candidate to do a turbo ls build so 6 liter 4080e we got the trans built by a h they did a killer job it's probably 900 000 horsepower capable comfortably this is a gen 3 lq9 6 liter so i pulled this out i built it with a texas speed drop-in rods pistons combo we've got texas speed cam we got prc stage 2.5 heads up so it's a it's a decently built little motor this motor should honestly handle a solid 13 1400 horsepower now we're limited a bit by our turbos is the vs racing 78.75 this turbo is going to cap out maybe around 900 950 or like absolute max and then we're eliminated by fuel system currently we've just got a single dtworks 450 pump and 92 pound detrox injectors and then we're using the stock truck intake so the engine the long block can handle again four digits the current configuration we have right now is probably good for 600 on pump 8 900 on e if we gave it a little more fuel so that's where we're at now and the plan for right now is to keep this thing as a nice comfortable street truck that's the point you know we've still got cruise control we've back integrated to the stock ecu to make it think it's still running the show so that way everything works as it should such as cruise control that's really the main thing we can't do on the terminator um and yeah you know just make it a nice solid little cruiser car i can jump in run to the hardware store do whatever i need to do uh but i can do burnouts at uh at will so that's the truck that's where we're at so the first project on the to-do list was to get our three-bar map sensor installed so we could actually read positive boost pressure so we get this thing screwed to the firewall we went with the kind of traditional remote mount gm three bar map style now the connector is different than the standard stock style connector so i bought this little adapter harness because it was just going to be quicker to get it than to order a connector and re-pin it and so on and so forth however unfortunately the connector for the map sensor side it was not the right connector looks identical almost the exact same just slightly different where the locking tabs are so since we weren't able to use that i did order another three bar map that goes in the stock location plugs into the stock connector however it was thirteen dollars so i was pretty skeptical on it but it was all we really had so we just went with it uh the next thing was to get fans in can't really drive around without radiator fan so that was a big thing holding this back so the first thing we need to do is get a relay setup mounted so i drilled some holes into this plastic we started mounting our msd solid state relay block now these bolts come with nuts for the back side but it wasn't going to be easy to get to the back side of this plastic housing so i just drilled some small holes and used the bolts to basically thread the plastic and honestly it worked out pretty great they snugged up nice and tight nice and solid and that allowed us to mount this in a nice super easy to access spot right there on the electrical center with all the other electrical stuff so with that done it was time to get the fans in now i decided not to go with a shroud on this truck i don't think it really needs it for what we're doing so we had to pull apart the front end to run the radiator fan zip tie deals that kind of punch through the radiator and hold the fans on so we had to take you know the intercooler off the hood watch off the ac condenser off and then we were able to access that and start installing our fans now in the terms of fans these are some temporary ones they might look really small they are really small so these are just a temporary solution for now to get us on the road and get us going so we start getting the fans installed start getting them wired up now i always go with 10 gauge wire on fans these fans probably won't need it but the fans that we are going to have in here long term will most likely need it and i you know i prefer to go overkill on wiring as opposed to under kill it's you can never really have too much wire too too heavy of a gauge of wire so i always like to plan for the future in case i got to put something crazy on that circuit um so we get those wired and get them hooked up to the msd and then we run our output from the holley so holley gives you this plug with a cap on it and then they give you another plug with the unterminated harness that has all your inputs and outputs on it so it makes it super easy all you gotta do is plug that in pick which one we want to be the output for the fans boom we're done now you know you could run one for each fan that way you can control each fan individually i don't really feel the need for that with this so we're gonna save some of those other outputs and just use one output to control both fans so we'll run that to the msd we'll just bridge it to the other channel and boom boom fans should turn on when they need to all right the truck is registered insured and we've got the final little odds and ends buttoned up so we replaced the thermostat housing fixed our coolant leak we were able to fill it and bleed it fully with coin got our fans in now these are not our permanent fans these are 10 inch mishimoto race fans i ordered the 16 inch fans it was one of those things i kept putting off ordering it because i'm like i don't need them just yet i don't need them just yet and the the time when it comes to drive the vehicle and start actually using it if at least for me it always comes up quick like i don't see it coming and i'm like like crap i can't drive it anywhere because it doesn't have fans so luckily i had these 10 inch race fans lying around i put them in the wiring and everything will be the same we'll just put the 16s in when we get those in but these will work for now they pull a ton of air there's not going to be pulling it from a ton of surface area so not the ideal setup but i think it'll be okay for for at least cruising around so we got those wired in with the msc solid state relay that's all sorted went ahead and did an oil change so we got our initial break in oil out from our few heat cycles we put into it we've got some more just straight for you breaking oil another cheap filter we're gonna run that for probably a hundred miles or so and then we'll start putting some good oil in it talk to matt apple so matt applesauce mechanics if you guys aren't familiar with him really great youtube channel it is his channel was the inspiration for this build just why this truck so exciting because this has been on my to build list for years and years and i've just it's gotten pushed back and pushed back and finally not only are we doing it but we did it i mean it's running and driving and it's it's time so we can start rolling into boost and see what happens nothing left to about to do it [Music] [Music] it's hard to tell if it's gonna be it's gonna stay lean when i get into it or not [Applause] i'll look at the log and see where it's at because it's like i'm trying to watch the air fuel and it does start going like when you when it starts making boost it starts coming down that's what i wanted for so long dude so long all right first test drive good um i didn't get it hard in the boost because the air fuels trying to go in the boost were pretty when i feel lean 14s so i want to check the log and see what happened as we got into boost um first all right a little louder here we fixed the thing uh the closed loop wasn't off i hadn't remoted and look at the logs uh the closed loop doesn't what that spring clip my fueling wasn't on which the amazing things about these is what i was trying to say i've been waiting to put my digital dash in and that would be a good time to have it one of those things i don't need that right now [Music] is oh [Music] we should definitely get gas because i might have had 87 in this thing i don't know i feel like the last time if is working oh that's sick we didn't have to do anything i thought we were going to have to give it dps let's do a sweater on the tps i mean i haven't seen it get out of negative pressure time with a zero all right guys well we still haven't even got it in the boost yet i was getting nervous that the boost gauge just wasn't working i'm only going i only got a quarter throttle so [Music] at least [Music] i was not expecting that there you go now it's making me [Music] that's it dude this is it that was right because this thing's probably only going to make like 500 may 6 max and like i was worried that wouldn't feel like anything because the miata makes five but it's a different kind of five it's like with these cars they should boil the tires off yeah like i said the whole time been just barely that i'm finally i'm still not even 100. yeah that time i saw double digits like five in it yeah it started cracking open sounded sick for a second there all right so we've got to address oh so good so good oh yeah sick all right well the first drive went super well first few drops i guess oh man that was a pretty funny saga so you know first starting out rolling into it trying to roll into it seeing that it was lean uh the closed loop wasn't on so that's where basically holly's reading the wide band and it's adjusting in real time so it's doing that and it's doing long term trim so it's reading the y band and slowly making a table that modifies your original table to fix areas where it's not at your target you set what the target what you want the target to be in certain areas and it'll slowly adjust the tune to do that but it also has your closed loop where it's going to be adjusting in real time so if it's lean it's going to add fuel and man the system's so good that you can literally just be like holly take the wheel and let it do its thing but that was off at first so that's why we were having a little bit of lean issue so matt added some fuel turned the closed loop on then it was okay so then i started rolling into it and i'm thinking man i've got to be making boosts like i'm going 25 30 throttle truck seems like it's moving out decent and i can't get the boost gauge to get above zero granted i wasn't flooring it because i was nervous but i was trying to just quarter throttle my way into boosting it just it would get to zero i'm like the boost gauge has got to be wrong so we come back we test it it all checks out fine boost gauge is right so okay we're really not getting this thing in the booth we literally haven't got it in the boost yet so last drive i finally i got on it i stabbed it you know 75 80 throttle and it just lit the tires up and do i can't tell you how i'm still smiling thinking about it that was like the culmination of work and one of those moments where you're like yes this is what i wanted you know this is what this was for and i could go on and on but very exciting now there's a problem we do have and that is our wastegate so we hit boost cut which is set at 15 psi now i have been concerned since i built this turbo kit that where i have my wastegate it's not going to be efficient enough to keep the turbo from making too much boost because it's got to come out do this 90 and then go through my screamer pipe however what's not helping us is that the wastegate has 12 psi springs in it so what we're going to do is put the softest spring in it a 4 psi spring and see how it does if we're still boost creeping and over boosting we've got problems we're going to have to fix it but we're going to run the softest spring we can so we can turn it down as much as we want and then we can add boost with the boost controller so we're going to pull this wastegate off and swap this spring [Music] all right so this is what was in there this is what came with it shipped i just put it on as it was shipped so i think these are two six pound springs and we're putting a four in so a lot less spring hopefully we won't have any over boosting issues so all right easy enough let's toss it back in all right gates back in with the softer spring checked everything everything seems good pretty much ready to rip one thing we really are going to need to do soon before we beat on this thing too much is crankcase ventilation so we've just got the two little breathers off the valve covers we need to do the motion raceworks breathers and two 10a in lines you know one off each valve cover to our catch can here there's a few things like that that need to get done but so you're drivable we're gonna drive her i can't i can't wait much longer so we're gonna take a little trip over to we're all done josue shop that's kind of like my inaugural test drive uh like first real drive with any project lately is to their shop because far enough to where you're really testing it but it's close enough to where something happens it's not the end of the world and if we're feeling froggy we can do a burn out in front of the shop so you know it's kind of a win-win so what's in the road see how the boost is now converter so it's it's this one [Music] eleven sweet it spiked to eleven but it was chilling at like seven eight okay so we have blue screen but at least with that small screen yeah i might have i just need to adjust oh all right well we got this thing to stop hitting boost cut uh it's still our wastegate priority meaning you know making the wastegate the easy route for the exhaust not great which we knew that when we did it that way i just wanted to do it that way because it looked cool and i could do the screamer pipe instead of putting it on the housing whatever point is with the four psi spring it makes like six seven eight uh and then it did spike up to eleven max so that's tolerable for now we are going to have to add uh probably a second gate which i mean one 44 mil gate's a little on the small side for a v8 anyway so we'll probably just add a second gate somewhere in the future past that uh one other issue we had is the trans temp was starting to get a little toasty when i pulled back in here it was 205 i went and drove it up and down the road just a little bit and it was it got up to like 2 25 2 30. so i parked it gonna try to put a fan on the trans cooler where it is now see how that is if it's still a problem we might relocate it to the back when we do a bigger trans cooler i don't know we'll have to see how that pans out i think mainly it needs a fan where we had to mount it it's not really getting direct air flow so i think if we add a good fan on there hopefully that will sort that issue out but yeah so need to do that one of the big things we need to do is install the digital dash we have the holley pro dash we're going to try to put it where the head unit is so we're going to do like a remote bluetooth head unit and basically that way we'll have a stock truck cluster like everything's normal but then we'll have the pro dash right there too so i'm going to start working on that stuff tomorrow but for now it's dark we're out of time she rips though i i am so stoked man finally getting to drive it around and it still runs and drives like the stock truck i wanted it to feel like the cruise control works really the only thing that makes it less deliberate is having the higher stall converter which is only really super noticeable because it's loud which i guess would be the other thing um so we could quiet it up but for now i'm having fun with the noise so anyway i'm gonna go ahead and wrap this up here i hope to see you guys next time more projects to do on this thing more driving to do i can't wait i just i love driving it and now that it's running and driving you know once we get all the little bugs sorted out we can start working on the aesthetics i've got a hd hood for it we can lower it put some you know bigger oem wheels on it and paint it make it look nice now now that it's mechanically cool it needs to fit the part aesthetically so anyway lots more to come on this thing and the other projects but for now that's a wrap so thanks for watching thanks for subscribing come by guys try not to touch the winds anymore because there's no cover anymore
